Application July 30, 1936, Serial No. 93,380

7 Claims.

My invention relates to pressure systems, and more particularly to means for converting fluid pressure into pressure upon another uid medium or upon another body of the same or a similar uid.

The system may be operated conjunctively with the apparatus shown and described in my copending application, Serial No. 93,379, led contemporaneously herewith.

Animportant object of my invention is to transfer the pressure of a water supply to a conned liquid body having a lower freezing point.

Another object is to exert continuous pressure through the intermediary ofV a conned body of liquid.

StillA another object isto provide an apparatus that may be buried below the freezing line in the ground, whereby water pressure may be converted to pressure upon a non-freezing uid, for usev during winter seasons.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the' course ofV the following description.

Inthe drawing, like reference characters designate similar parts in the several views.

Figure 1 is a vertical section-of a system embodying my invention.

Figures 2.and3 are enlarged elevations, partly insection, showing details of the system.

Referring more in detail to the drawing, the reference number 4 generally designates a pit in the ground, in which is housed an embodiment of my invention. An inletrconduit 5 supplies pressure uid tothe system; e. g., water under pres- Sure.

Two tanks 6 and I are arranged tol alternately receive the Supply from the conduit 5. A header 8 distributes the water supply'from the conduit to the tanks. Valves 9 and I0 respectively control the ow to tank 6 and to the tank 1. The valves'comprise balls I2 depending from opposite ends of a walking beam I3. Each balls arranged tof engage a" seat I4.

Levers I5 are pivotally mounted on lugs I6 within the tanks. Rods I1 and 38, depending fromy the'ballsl 2 inthe tanks 6 and I respectively, have; circumferential grooves |8 for receiving endsV of the levers I5'. The lower ends of the rods il and 38 have sockets |9;

Each of the tanks 6 and 'I has abottom outlet 28; Ball valves 2| and 3| are arranged to control the outlets of-tanks 5 and 'I respectively. Bars' 22.,v mounted on the balls' 2| and 3|, have sliding itswith the sockets' I9. Lugs 23 on the bottoms 24 of said tanks pivotally' carry levers 25,

Slidably mounted onl the rods. |1- and 30 are floats 28 and 29, in the tanks 6 and'l respectively. A discharge conduit 32 receives the liquid discharged at the outlets 28 of the tanksv 6 and 1.

Another pair of tan-ks33 and 34Y are comprised in the system. The tanks 'I and 33 are connected at their heads by a pipe.v 35 and the tanks and 34 are connected at their Vheads by a pipe 35.

A pressure exhaust pipe 31 is connected by branch-es 38 and 39 to the upper portions ofthe tanks 33 and 374 respectively; Ball check valves 48-and 41| are-disposed in the branches 38 and 39 respectively. Each check is arrangedv to permit the flow of pressure fluid into the tanks 33 and 34, but to prevent the escape of pressure fluid at such points.

A pressure discharge pipe 42` is connected by branches 43 and 44 to the lowerrportionsof ythe supply system that is under pressure, and theV discharge conduit is connected with a reservoir, a waste disposal, a sewer, or the like.

The pipes 31 and 42 may be connected'respectively with the exhaust and intake of any apparatus employing fluid pressure; ei g., the apparatus shown andl described in my' said co-pe'nding application for patent.

In the operation' of the present system, liquid pressure is introduced into the' header 8; In the position shown in Figure l, the Valve 9 is open and the valvey 2| is closed, and the tank 6 is 'almost filled withV liquid, causing theoat 28 to rise almost to the upper limit of its movement. Figure 1 shows the position of the float 28 just as it strikes the levers operating the valve 9. Additional liquid fed into the tank 6 will cause the float to rise until it closes the valve 9. Filling of the tank 5 with liquid expels air therefrom, through the pipe 36 into the tank 34. This movement of air increases the air pressure in the tank 34. Closing of the valve 9 forces therod I1 downward, which opens the valve 2|, for thedischarge of the liquid from the tank 6 into the outlet conduit 32. Of course the'oat 28'descends and rests on the crossbars 2T, as shown by the float 29 in tank As soon as the float 28 closes the valve 9, the valve I0' is causedY to open through the intermediary of the walking beam I3; and the valve VCIO 3l is causedfto close sincethe rod 370 is liftedbyr` the walking beam Yand the greater weight Vof the Y ball valvelSlV causesgit to drop closed.

Thereupon liquid from the conduit 5 empties* into. the tankY 1',fcausing Ythe float 29vto rise until' it strikes the levers Vl5 voperatimgf.the valve i0.

Air pressure in the tank l, causedbythe risingVL liquid, is forced from the tank'l through the pipe into the tank 33.

`When the float 29 closes the valve I0, openingV the valve 3|', liquid in the tank 'l is discharged into` the outlet'pipe 32. At the Sametime the Il; valve 9 is'openranrd the valve `'A.Iclc' sedand the Y cycle of operation of the tanks Gland Tis being repeated. Y Y, Y, Y Increase of air pressure inthe tank 33V causes expulsionof fluid from ,s 'aid tank past the check Y Y valve45, through the branch-43 ,andVV through theA Y Vdischarge pipe 42; The ,pressurein thefdbranchV V4,4 from the'tank 33 holds the` check 46 in a closed position. Spent fluidV from the apparatus 30 that` isbeing'actuated by the iluidV pressure isY returned beY of anydesired type utilizing uid through Ythe Ypipe. 3.1, through branch39, past Y Hcheck 4| and intofthe'tank 34. The spent Vfluid Y goes ,into the tank 34Y because the pressure'there- V in is less than 'in thetank. 33 (the pressure in the tankv33 holds the ycheck 4l) in aclosed position). It is to be understood that theV apparatus 50 may pressure and may be'situated where desired. Y Y Y When the pressure in the'tank 33 falls below the pressure in the tankk 34, the pressure in the tankl34 opens` thecheck46 and closes the checks 4| and k45;Y Thereupon the pressure buildsv up again inY the tank 33 by means ofthe pressure :introduced'byithe pipe 35. At'thesame time,

'the fluid'pressure in the tank 34 isA discharging Y' past the check 46,Y through the branch44andV through the discharge 42` toperform its Work.`

Spent fluid is returned through the pipe 31 to the tank 33, and. then the cycle of operation of by the system shown and described herein.
